Cisco IOS Auto SmartPort macros dynamically configure ports based on the device type detected on the port. When the switch detects a new device on a port it applies the appropriate Cisco IOS Auto Smartports macro. When a link-down event occurs on the port, the switch removes the macro. For example, when you connect a Cisco IP phone to a port, Cisco IOS Auto SmartPorts automatically applies the IP phone macro.
MAC Address-Table Move Update allows a switch to provide rapid bidirectional convergence when a primary (forwarding) link goes down and the standby link begins forwarding traffic. Catalyst 4500 Series Switch, Cisco IOS Software Configuration Guide - Cisco IOS XE 3.9.xE and IOS 15.2(5)Ex...

The Catalyst 4500 series switch supports trusted boundary, which uses the Cisco Discovery Protocol (CDP) to detect the presence of a Cisco IP phone (such as the Cisco IP Phone 7910, 7935, 7940, and 7960) on a switch port. If the telephone is not detected, the trusted boundary feature disables the trusted setting on the switch port and prevents misuse of a high-priority queue.

Note Cisco IOS Command Reference Guides for the Catalyst 4500 Series Switch. If a command is not in the Cisco Catalyst 4500 Series Switch Command Reference , you can locate it in Cisco IOS Master Command List, All Releases. Managing the System Time and Date You can configure the system time and date on your switch manually or automatically by using Network Time Protocol (NTP).
Cisco’s implementation of NTP does not support stratum 1 service; it is not possible to connect to a radio or atomic clock. We recommend that the time service for your network be derived from the public NTP servers available on the IP Internet.
Switch F Workstations If the network is isolated from the Internet, Cisco’s implementation of NTP allows a device to act as if it is synchronized through NTP, when it is not. Other devices then synchronize to that device through NTP.

WS-X4908-10GE, WS-X4904-10GE, and WS-C4900M. To use an SFP+ in an X2 port to obtain 10-Gigabit Ethernet bandwidth, the Catalyst 4500 series switch supports OneX Convertor modules. When you plug a OneX Convertor module into an X2 port, it converts the X2 port into an SFP+ port into which you can plug in an SFP+.
On the Catalyst 4503, 4506, and 4507R series switches, this capability is automatically enabled. Prior to Cisco IOS Release 12.2(25)SG, you could enable either the dual wire-speed 10-Gigabit Ethernet ports or four alternatively wired Gigabit Ethernet SFP uplink ports.
SFP 13 In Cisco IOS, ports 1 through 18 always exist. This means that you can apply configurations on them and they display in the CLI output. However, only the X2 or the SFP ports can be active at any particular time. For example, if an X2 is plugged into the second hole, the X2 port 2 is active and SFP ports 9 and 10 are inactive.

Jumbo Frame Support, page 9-35 • Configuring MTU Sizes, page 9-37 • Ports and Modules That Support Jumbo Frames The following ports and modules support jumbo frames: Catalyst 4500 Series Switch, Cisco IOS Software Configuration Guide - Cisco IOS XE 3.9.xE and IOS...
Maximum Transmission Units The Catalyst 4500 series switch allows you to configure a maximum of 32 different maximum transmission unit (MTU) sizes system wide. This means that the maximum number of different MTU sizes that you can configure with the system mtu, mtu, ip mtu, and ipv6 mtu command on all Layer 2 and Layer 3 interfaces combined is 32.
Page 476
Note The Catalyst 4500 series switch does not compare the packet size with the MTU at the egress port, but jumbo frames are dropped in ports that do not support them. The frames can be transmitted in ports that do support jumbo frames, even though the MTU is not configured to jumbo size.
Interacting with Baby Giants The baby giants feature, introduced in Cisco IOS Release 12.1(12c)EW, uses the global command system mtu size to set the global baby giant MTU. This feature also allows certain interfaces to support Ethernet payload size of up to 1552 bytes.

Data routes are sometimes less than optimal. For example, it is possible for the router to be forced to resend a packet through the same interface on which it was received. If this occurs, the Cisco IOS software sends an ICMP Redirect message to the originator of the packet telling the originator that the router is on a subnet directly connected to the receiving device, and that it must forward the packet to another system on the same subnet.
URL: http://www.cisco.com/en/US/docs/ios/ipapp/configuration/guide/ipapp_hsrp_ps6350_TSD_Products_Confi guration_Guide_Chapter.html To enable the sending of ICMP Redirect messages if the Cisco IOS software is forced to resend a packet through the same interface on which it was received, enter the following command in interface configuration mode:...

When the spanning tree protocol is running in a VLAN, a spanning tree topology change notification (TCN) is issued by the root switch in the VLAN. A Catalyst 4500 series switch that receives a TCN in a VLAN for which IGMP snooping has been enabled immediately enters into multicast flooding mode for a period of time until the topology restabilizes and the new locations of all multicast receivers are learned.
When a spanning tree root switch receives a topology change in an IGMP snooping-enabled VLAN, the switch issues a query solicitation that causes an Cisco IOS router to send out one or more general queries. The new command ip igmp snooping tcn query solicit causes the switch to send the query solicitation whenever it notices a topology change, even if that switch is not the spanning tree root.
